  1. Emphasis is placed on the dosimetry for radon and daughters, rather than on monitoring and instrumentation. The objectives of the meeting were to exchange scientific information, to identify problem areas in radon-daughter dosimetry, and to make any observations or recommendations by the participants through issuance of this report. The discussion topics included the history of dosimetry for radon and daughters, human data, aerosols, deposition and movement in the respiratory tract, dose calculations, dose-to-working-level-month (WLM) conversion factors, animal experiments, and the development of regulations and remedial criteria for reducing population exposures to radon daughters. This report contains a summary of Workshopmore » discussions plus individual statements contributed by several of the participants. The outstanding problem areas from the standpoint of dosimetry appear to involve the appropriate lung organ mass to be used (average lung-tissue dose vs. high-level local dose); recognition of the discrete, rather than continuous, structure of the mucus; lack of knowledge about lung clearance; the variability of dose with the degree of disequilibrium and the unattached fraction of radon daughters for a given WLM; and questions about the character of uranium mine atmospheres actually breathed in the older mines from which much of the epidemiological information originates. The development of criteria for taking remedial action to reduce exposures involves additional concerns of basing long-term risk assessment on short-term sampling and applying WLM data for miners to general populations.« less
  2. Separate abstracts are prepared for the six main chapters on the various characteristics of the transportation sector. Chapter 7 provides the compilation of reference materials, and additionally, sections are devoted to a glossary, keyword index, and permuted-title index. (MCW)
  3. This document is the fourth in a series of supplements to ORNL-5198, Transportation Energy Conservation Data Book: Edition I (EAPA 3:527). The Data Book series is being compiled and published by ORNL under contract with the Transportation Energy Conservation (TEC) Division of the Energy Research and Development Administration (ERDA). Data on transportation characteristics, energy consumption, and other related variables are presented in tabular or graphic form. For the user's reference, a glossary, a bibliography, energy conversion factors, and an index to information presented in Supplement IV are provided. Some of the specific items presented on transportation modal characteristics include fleetmore » vehicular stock data, automobile choice and ownership characteristics, information describing commuting and long distance travel patterns, new car sales by market segment, electric vehicle production, and statistics on bicycle stock and usage. Transportation energy demand projections in general, and in detail for the marine sector, are presented, as well as sales-weighted miles per gallon figures by weight of automobile, model year, and automobile producer. Other transportation-related information included in Supplement IV are a graphic presentation of President Carter's tax-rebate schedule, a comparison of the nominal and real price of gasoline, and a descriptive list of the current safety standards. Finally, detailed data on the US total population and its migration patterns are presented. The second edition of the TEC Data Book will update and integrate the information provided in Edition I and the Supplements. The planned date of publication for this document is October, 1977.« less
  4. This document is Supplement I to Edition I of the Transportation Energy Conservation Data Book, ORNL-5198, which was published by Oak Ridge National Laboratory in October 1976. The first edition and this supplement are intended to provide a desk-top reference for use by the Transportation Energy Conservation Division of the Energy Research and Development Administration. This supplement contains statistics which update and augment data presented in Edition I. A variety of tables, charts, maps, and graphs are used in this volume to present statistical data on energy use and energy related activity through the following topics: (1) Characteristics of Transportationmore » Modes including information on Air, Rail, Water Vessels, and Pipelines; (2) Energy Characteristics including information on Energy Consumption and Energy Intensity; (3) Government Impacts and Government Regulations. A list of references is provided at the end of each chapter supplement, and an annotated bibliography and glossary are included at the end of the supplement. In particular, nonhighway transportation activities received less emphasis than highway activities in Edition I. Therefore, this supplement presents additional data in this area. Also, detailed data on fuel consumption and energy intensiveness of the various modes is included in this document. Periodic updates will ensure the availability of recently released data.« less
  5. A machine readable data base has been created by the Regional Information Group, Regional and Urban Studies Section, Energy Division, Oak Ridge National Laboratory, to provide documentation for the energy, environmental, and socioeconomic data bases and associated software maintained at Oak Ridge National Laboratory. This document is produced yearly by the Regional Information Group to describe the contents and organization of this data base.
